Skin dz?

I have a white leghorn about 3 weeks old and about a week ago developed a raw rear end that is now scabbed over. It looks like it's healing on its own and feathering back in. Today I was examining it and under one wing the skin looks like it's peeling away from it's chest. Just a small patch. Does not look like it's trauma.

The chick doesn't act sick or abnormal compared to the other chicks. It's a pretty fiesty chick, eats and drinks well. Is very active.

I did take a closer look at it's vent. The chick is discharging a clear (yellowish?) liquid. That's what is causing the raw area. That coupled with the skin peeling away under its wing are odd symptoms. Other than that, it's an active growing chick.

I'm also keeping a very close eye on the other chicks to make sure this isn't something that will spread.
